The assay of pneumococcal capsular polysaccharide by immunodiffusion
Journal of Immunological Methods, 1974Abstract A simple gel diffusion technique was compared with the quantitative precipitin test for evaluating concentrations of pneumococcal polysaccharide. The analysis showed that results with unknown samples compared closely by the two methods.

Bacterial capsular polysaccharides and exopolysaccharides
2010Bacteria often produce an external layer of polysaccharides, characterized by a definite primary structure, which in turn is responsible for sometimes remarkable physicochemical properties. Although the number of monosaccharides which constitute the polymers is rather low, the great number of different polysaccharides defined up to now shows the ...

Genetics of Capsular Polysaccharide Production in Bacteria
1990A feature of many bacteria of diverse genera is the production of extracellular acidic polysaccharides. These polysaccharides may be organised into distinct structures termed capsules, or may be excreted as an extracellular slime. However, this distinction is arbitrary and in practice may be of no functional significance.

Chemically Modified Capsular Polysaccharides as Vaccines
1988Capsular polysaccharides have assumed an important role as vaccines against disease caused by bacteria in humans. The concept of using pure definable polysaccharides devoid of their accompanying complex bacterial mass is technically elegant and is obviously capable of extension into other areas of immunoprophylaxis.

Method for producing capsular polysaccharides [PDF]
, 1994 Structurally altered capsular polysaccharides are produced by mutant bacteria. These polysaccharides are isolated by selecting a wild type bacterial strain and a phage producing degradative enzymes that have substrate specificity for the capsular ...

[Bacterial capsular polysaccharide--a review].
Wei sheng wu xue bao = Acta microbiologica Sinica, 2012The study on bacterial capsular polysaccharide is deeper with the development of the molecular biology, saccharide chemistry and immunology. Not only the character and structure of bacterial capsular polysaccharide was researched, but also the genes related to the synthesis, regulation and pathogenicity.

Capsular Polysaccharides of Staphylococcus aureus
1990The existence of capsular polysaccharides in Staphylococcus aureus has been demonstrated by immunological, biochemical, morphological and epidemiological studies. Eleven serotypes have been described and the corresponding antigens contain aminuronic acids and no neutral sugars.
